Beispiel
#Include ADwinPro_All.inc
#Define module 2
gain_B
#Define 2
#Define ex_B 4
Dim i As Long
Dim Data_1[10] As Long
LowInit:
Rem set mode single shot and select all channels
P2_SG_Mode(module,1,0FFH)
Rem set gain, filter, and excitation voltage of all bridges
For i = 1 To 4
P2_SG_Init(module, i, gain_B, 1, ex_B)
Next
Rem start sampling
P2_SG_Start(Shift_Left(1,
Processdelay = 40000
Event:
Rem wait for end of sampling
P2_SG_Wait(module)
Rem read 8 values
P2_SG_Read(module, 8, Data_1, 1)
Rem start next sample
P2_SG_Start(Shift_Left(1,
Rem get bridge voltage
For i = 1 To 4
FPar[i] = P2_SG_Convert(Data_1[i], gain_B)
Next
Rem get sense voltage
For i = 5 To 8
FPar[i] = P2_SG_Convert(Data_1[i],
Next
Rem calculate relative strain
For i = 1 To 4
FPar[i+8] = FPar[i] / FPar[4+i]
